“…Given the strong geological heterogeneity generated by the karst system in which fractures and conduits are often developed and hard to quantify, conventional hydrogeological investigation and numerical model of groundwater flow are difficult to provide a primary sound hydrogeological description (Lauber and Goldscheider, 2014;Pavlovskiy and Selle, 2015). In such cases, a multiparametric approach integrating hydrochemical and isotopic data is always useful to diagnose the groundwater flow system (Pavlovskiy and Selle, 2015;Wang et al, 2013).…”

“…Good K/Mg temperature estimates indicate that dissolved Na and Ca have not attained the fluid-rock equilibrium. This indicates that no new water-rock reaction equilibrium attempted to form in the ascending thermal groundwaters (Wang et al, 2013).…”

Five thermal springs, twelve non-thermal springs, and two lake water samples from the northwestern part of Rwanda were studied to assess their chemical characteristics and infer the formation mechanism of the thermal waters. Multicomponent mineral equilibrium (MME) geothermometer calculations at Gisenyi prospects with the highest in situ measured temperature (73.1°C) showed the reservoir temperature of 90±6°C. The MME temperature estimates agreed well with Silica-based, K-Mg and Mg-Li geothermometers while the other cation geothermometers (Na-K, Na-K-Ca, Na-K-Ca-Mg, and Na-Li) results are unreliable. Most of the non-thermal springs are Ca-Mg-HCO 3 water-type while the thermal spring waters were majorly Na-HCO 3 . The δD composition varied from -16.6 to -5.9‰ and from -11.8 to -5.0‰, while the δ 18 O ranged from -4.17 to -3.5‰ and -4.32 to -2.7‰, for thermal and non-thermal springs, respectively. All isotopic ratios scattered around the meteoric water lines, thus indicating their similar meteoric origin. In addition, there was no observable δ 18 O positive shift speculating less extent of water-rock interactions while geogenic CO 2 ingress into the waters has been ascertained by both isotopic and chemical component ratios. We proposed a circulation mechanism of the thermal waters for the study area.

This study aims to hydrochemically characterise three CO2-bearing springs representing distinct hydrofacies in NW Gorveh (western Iran) and interpret them in the light of their geological setting. The results of laboratory measurements of elemental concentrations, stable oxygen, carbon and hydrogen isotopes, dissolved and particulate organic and inorganic carbon (DIC, DOC, POC, PIC) and alkalinity are combined with in situ measurements of pH and temperature. Parameters such as alkalinity, DIC, Ca 2+ and pCO2 concentration display a strong, positively correlated values, with systematic decrease from the spring vent in down-flow direction for the three spring systems. The inverse correlation of pH and δ 13 CDIC is caused by CO2 degassing. The δ 18 O and δD values show no significant variation, related to minor or no evaporation due to normal ambient temperatures. The low concentration of POC and PIC and DOC compared to that of DIC and the lack of correlation between them reflects predominant inorganic carbon in these fluids.Spring I is oversaturated in calcite with additional dissolution of CO2, and despite high concentrations of Na + and Cl -, undersaturated in halite, indicating a fluid of geothermal origin and/or reflecting steady state dissolution. This is related to water-rock interaction processes with carbonate and evaporitic rocks, 2 that affected the isotopic signature of δ 18 O, which is shifted to the right of the global meteoric water line. Spring I also represents a partially equilibrated and mature (deep) chloride type water. Spring Ⅱ and Ⅲ are less saline and represent a different fluid circulation and/or reflecting shorter residence time.The two latter springs are characterised by peripheral (shallow) dilute chloride-bicarbonate type waters.Decreasing key parameters especially in Spring Ⅲ during the winter suggest that superficial mixing with rain and meteoric water results in high temporal variations. Cation and stable carbon isotope geothermometry applied to the studied springs reveal an average reservoir temperature of ~210, 110 and 90 °C for Spring I and II and III, respectively. The geochemical and isotopic data allowed to depict a conceptual model where the hydrothermal reservoir for Spring I is residing in carbonate and evaporitic rocks (most likely the Qom Formation) situated at a depth of 3-4 km whereas those of Spring Ⅱ and Ⅲare likely sourced from a shallower depth (1-2 km) in correspondence with carbonate and porous and permeable volcanic rocks.Integration of hydrofacies with conceptual hydrological and geological models forms the base towards a proper understanding of water circulation patterns, increasingly important for sustainable water management and geothermal applications.insights into fluid-rock interaction processes, origin of waters, reservoir depth and temperature (e.g. Giggenbach and Glover, 1992). Considerable research has been devoted to address the elemental composition and isotope characteristics of hydrothermal waters and related inorganic carbonate deposits (e.g.
